SPECIFICATION forming part of Letters Patent No. 748,073, dated December 29, 1903.

.Application filed March `27, 1902.`

To all whom it may concern:

` Be it known that I, ARTHUR HIRSH, a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Upholstery- Spring Supports, of which the following is a specification.

This invention relates to improvements in upholstery-spring supports, and refers more re specifically to an improved substructure formed of intersecting wires and including improved means for uniting the springs with the substructure. Thesalient object of the invention is to x 5 provide a simple, highly-efficient, and cheap construction, in which the lower supportingframe is composed of intersecting wires which are rigidly united with each other, and the upholstery-spring with both, by means of a 2o simple cheap metal clip.

The invention consists in the matters hereinafter described, and more particularly pointed out in the appended claims, and will be more readily understood from the follow- 2 5 ing description by reference to the accompanying drawings, forming a part thereof, and in which-- Figure l is a view, partly in transverse verl tical section and partly in side elevation, of

3o the lower end portion of an upholstery-spring and the supporting-frames to which itis attached. Fig. 2 is a plan view of the supporting-frame with Vthe spring removed, and Fig.

3 is a perspective view of the attaching-clip.

3 5 Referring to said figures, l and 2 designate a pair of supporting wires or rods arranged in intersecting relation and forming the subframe proper, upon which the upholsterysprings are supported. 3 designates as a 4o whole the lower end portion of an upholsteryspring interengaged with the supportingframe, and 4 the sheet-metal clip, whereby the attachment or securing together of the parts is eected.

The supporting clip 4 comprises, essentially, a base portion 5, which forms a support against which the end of the spring may act, and eye portions connected with said base and extending outside ofthe plane of 5o the latter, in this instance `formed by a cir-v cumferential flange 6 and through which are formed retaining eyes or apertures 7 and 7.

Serial No. 100.278. (No model.)

The base of the clip is likewise provided with au aperture 8, which receives a deiiected or U -shaped loop portion l', formed in the crosswire l. In the particular embodiment of my invention shown herein the base of the clip is arranged to overlie the main cross-wire l, and the loop of the latter is accordingly extended upwardly through the aperture 8, while the cross-wire 2 isinserted at right angles to the cross-wire l through the eyes 7 and 7' of the clip and under or in engagement with the loop l', the vertical height or length of the loop l and the location of the holding-eyes 7 and 7' being such that when the parts are int-erengaged, as described, the cross-wires will be held in firm bearing with each other at their points of intersection and the base in irm bearing with the underlying cross-wire. The location of the eyes 7 and 7' is sufficiently above the upper surface of the baseplate 5 to admit of passing the lower coil 3 of the spring thereunder, as shown clearly in Fig. Lwhile the diameter of the clip or the distance between the flange portions thereof containing the eyes is such that when the coil of the spring is engaged therewith movement of the spring in the direction of the length of the straight cross-wire 2 is prevented. Preferably, and as shown herein, theeyes 7 are 1ocated above the base-plate a distance approximating but somewhat less than twice the diameter of the wire of the coil, so that when the coil'has been threaded underneath the cross-wire 2 to an extent approximately equal to one revolution its extreme end 3' passes into wedged engagement with the upper surface of the base-.plate and the overlying portion of the coil which directly engages the cross-wire 2, thereby causing the spring to pass into a firmly locked or wedging engagement. The pitch orinclination of the coil of the spring and its natural resiliency causesthe lower coil to press upwardly against the cross-wire 2 and downwardly against the base portion of the clip, so that all of .the parts are absolutely locked or clamped together when the parts are in assembled relation, and owing to the peculiar wedging of the extreme end of the coil underneath the overlying coil, as hereinabove described, the spring in being rotated into engagement with the clip reaches a position ICO where it becomes positively locked -against further rotation. The result is that the clip and intel-engaging eyes of the latter and loop l may be so constructed that the parts may be loosely placed together, but nevertheless be held absolutely rigid with each other when the spring is interengaged in the manner described. It will be obvious that -disengagement of the parts may be accomplished With the greatest facility by simply rotating the spring in the reverse direction, applying suficient force to release the wedged engagement hereinbefore described. Itis also to be noted that the parts are not only held in rigid relation to each other, but the spring is positively supported upon a circular base, and the lower coil is fastened rmly against the base by the overlying cross-wire, so that the spring is held absolutely rigid against tilting movement in any direction.

It will be obvious that the construction is an extremely inexpensive one, quickly and conveniently assembled, and, further, that the supporting-wires are practically devoid of longitudinal elasticity or stretching capacity, one of them being entirely straight and the other having its loop portions engaged with the clip-aperture in such manner as to prevent any longitudinal elasticity which might be due to the vprovision of the loops or bends in the wire.

It will be obvious that the details of construction may be modied without departing from the principle of the invention, and I do not, therefore, limit myself to the details shown, except to the extent that they are made the subject of specic claims.

I claim as my inventionl. The combination with a coiled upholstery-spring, and intersecting supportingwires, of means unitingsaid parts comprising a clip having av horizontally disposed base portion, an eye flange portion upon the base portion, and one or more eye-apertures formed through said flange portion in a plane outside of the plane of the base, one of said united members being threaded through the eye llange portion of the clip and locking the parts together.

2. In combination with a coiled upholsteryspring, and intersecting supporting-wires, means uniting said parts comprising a clip having a base portion and a relatively elevated portion through which latter are formed a plurality of eyes, said eyes being located in a plane substantially parallel with, but 4removed from the plane of the base, one of said united members being threaded through said eyes and the lower end of the spring being interwoven with the supporting-wires whereby the parts are locked in clamping engagement.

3. In combination with a coiled upholsteryspring, intersecting supporting-Wires and a clip uniting said parts comprising a circular base portion upon which the spring rests, a relatively elevated portion, and a pair of diametrically opposite eyes formed through said elevated portion, substantially parallel with but above the plane of the base, one of said intersecting wires being passed through said eyes and above the portion of the spring.

4. In combination with a coiled upholsteryspring, intersecting supporting-wires, one of which is provided with a bend to confine the opposite wire at their points of intersection, and a clip uniting said parts, comprising a circular base member above which the end of the spring is located; a recess in the central portion of said base into which the deflected portion of the bent wire extends and a pair of eyes formed through the clip transversely opposite the recess which receives the bend of the wire through which the intersecting Wire extends, for the purposes set forth.

5. In combination with a coiled upholsteryspring, and intersecting su pportin g-wires one of which is provided with a bend to partially embrace the intersecting cross-wire, means uniting said parts comprising a circular base member provided with a central recess to receive the bend of the bent wire, upstanding eye portions diametrically opposite each other and eyes formed through said eye portions, said eyes being located above the upper surface of the base a distance greater than the thickness of the wire of the spring whereby the coil vof theflatter may be passed between the base and the wire inserted through said eyes.

6. In combination with a coiled upholsteryspring and intersecting supportingwires, means for uniting said parts comprising a metal clip, provided with a base portion adapted to lie in a substantially horizontal plane and having eye portions arranged outside of the plane of the base provided with transverse eye-apertures, one of said supportingwires being threaded through eyes ot' the clip and the spring being interwoven therewith, whereby said parts are firmly locked together for the purpose set forth.

7. In combination, a coiled upholsteryspring, a supporting-wire provided with an upWardlydeflected bend intermediate its length and means uniting said parts comprising a clip having a base portion lying upon the supporting-wire and an aperture formed through said base portion through which the deflected portion of the supporting-wire is extended, and means interlocking the end of the spring with the portion of the wire exposed through said aperture Whereby the base portion of the clip is clamped between the spring and supporting-wire.

8. In combination a coiled upholsteryspring, a supporting-wire and means uniting said parts comprising a clip having a flattened, horizontally-disposed base portion arranged to rest against the supporting-wire, an aperture formed through the base portion of said clip and exposing the supporting-wire therethrough, and means interlocking the end of the supporting-spring with the support- IOO ing-Wire through said aperture of the clip, for the purpose set forth.

9.
